I think that you should upgrade to the latest Telerik version.
In 2009 there was no IE10 - so I suppose that it is not supported in there.
Since IE10 is still in release preview phase - I suppose that even the latest Telerik version can have a few issues under it.

You should upgrade RadControls for asp.net ajax to version 2012.2.607 or higher. Here are detailed steps how to upgrade to another version or license.

I am having similar issue with IE 10. I am using Telerik (version 2010.3.1317.20) on asp.net 2.0 website. As this is the last supported version from Telerik for asp.net 2.0 websites, I am unable to update to the latest version.

Any other help will be really appreciated. Thanks

Error: "SCRIPT5007: Unable to get property 'documentElement' of undefined or null reference

As most of the computers have automatically upgraded to IE 10, we would like to know urgently what else we could try to make telerik controls to work. Issues being with controls like RadCombo and RadWindow for me (Radbutton works though).

We are aware of an IIS known issue for IE10 that might be related to the unwanted behavior you are experiencing on your site. There is a patch provided by Microsoft that is necessary to be applied to the server.

If this solution doesn't help you please try to isolate the issue in a sample page that matches your setup with detailed reproduction steps, so we will be able to reproduce and examine it locally on our site.
